I have a ton of film photos from our honeymoon to Europe (way back in 1994) that I would like to fix up with a little bit of processing.

I only have an Epson Rx650 scanner, which scans prints ok but apparently also scans negatives which I was thinking of doing (if I can find the negatives).

Can anyone suggest the best way of doing this (size, dpi, settings?) if I a) scan the prints or b) scan the negatives?

I assume that scanning the negatives may give me a better end result but I can't for the life of me work out how a physical film negative will end up on my computer screen as a colour image - is there some other software that I will need other than PS CS4?
